Clinical approach to small psittacines and passerines

In Practice, Volume 48, Issue 4, Page 181-189, May 2026.
Background: The most commonly encountered small avian species in clinical practice are psittacines, such as budgerigars, cockatiels and lovebirds, and passerines, such as finches and canaries. These birds are increasingly presented for veterinary treatment, with owners expecting a high standard of care.

A Case Report of Avian Polyomavirus Infection in a Blue Fronted Parrot (Amazona aestiva) Associated with Anemia

Case Reports in Veterinary Medicine, Volume 2015, Issue 1, 2015., 2015
An adult Blue Fronted Amazon parrot (A. aestiva) presenting with emesis, apathy, undigested seed in feces, and severe anemia was treated for approximately 2 months. Upon radiographic examination, an enlarged kidney was the only alteration. PCR for avian Bornavirus, Circovirus, and Polyomavirus was performed for the feces and blood.

Unveiling Novel Viral Diversity, Biogeography, and Host Networks in Wildlife Through High‐Throughput Sequencing Data Mining

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Analysis of 57 536 high‐throughput sequencing datasets uncovers a vast, hidden world of viruses in wildlife. The researchers reveal significant geographic and host‐specific patterns of viruses, and their surprising cross‐species transmissions, such as avian flu viruses infecting goats.
